Four weeks later, human skeletal remains were discovered in a vacant lot in north Liberty County.

A two-day search yielded 85 percent of the skeleton for DNA testing. The Liberty County Sheriff's Office says the results confirm the remains are those of Pargas.

On the first anniversary of her disappearance, one of her five daughters wrote this on the Missing Pieces Network's Facebook page: "It still hurts as if it was just yesterday. I still wish this was all a dream. We don't lose faith that one day my mom will return back and we will be a family again."

Hope is what they held on to. Now authorities are asking the public for information about Pargas' murder.

How did this single mother of five end up dead in a remote area in Liberty County? That is the question investigators hope to answer.
